I am a 5th year PhD student at Cornell University, working with Prof. Alyosha Molnar. Previously, I received my B.S. in Electrical and Computer Engineering and a Minor in Mathematics from Duke University in 2012. I spent the summer of 2016 as a hardware engineer at Google ATAP. |

I'm interested in full-duplex capable software defined radios, and especially enjoy working on system level ideas to inform analog circuit designs. I also like thinking about the entire vertical stack from testability to algorithms and new networking protocols. |

We present an SDR in which a distributed TX circuit cancels the transmitted signal at the RX port while adding constructively at the antenna (TX) port. Measurements from the transceiver implemented in 65-nm CMOS show a frequency tuning range of 0.3-1.6 GHz with TX-RX isolation >23 dB and transmitted power up to 19 dBm. |
|
We analyze theoretical limits for figures of merit such as isolation and efficiency for the transceiver we introduced at RFIC 2016. |
|
One of the remaining challenges in software defined radio hardware is the construction of a flexible RF system capable of duplex operation. Specifically, transmitting and receiving on the same antenna across a wide band of frequencies presents a significant challenge. We present some of the primary challenges that arise in this space, as well as some interesting published and potential solutions. |

An ideal software defined radio requires a reconfigurable, integrated and widely-frequency-tunable transceiver that is capable of supporting different duplexing schemes. We introduce an FDD and TDD capable single antenna transceiver that achieves >25dB of isolation over the 0.3GHz-1.6GHz band. |
|
We introduce a fully integrated, wideband, duplexing transceiver with baseband noise cancelling duplexing LNAs. We achieve 30dB of isolation in RX band for a 0.1GHz-1.5GHz frequency range during FDD operation. |
|
We introduce a circuit level modeling technique to accurately simulate 3rd order nonlinearity for passive mixers. |
